C -- ENGINEERING, FABRICATE, INSPECT, TEST OF AN OFF GAS EXHAUSTER SOL n/a DUE 030600 POC Annette P. Midcalf, (803)952-6293 E-MAIL: click here to contact Annette Midcalf by email, annette.midcalf@srs.gov. Westinghouse Savannah River Company (WSRC), Management and Operating contractor for the U.S. Department of Energy's (DOE) Savannah River Site (SRS) located near Aiken, South Carolina, is seeking expressions of interest from potential subcontractors for the engineering, fabrication, and testing of an Off-Gas Exhauster (Blower) assembly. This equipment will be used at Savannah River Site's (SRS) Defense Waste Processing Facility (DWPF). The supplier shall furnish all necessary activities for the design, manufacture, inspection, testing, documentation, and delivery of highly reliable close tolerance, off-gas exhauster to transfer process off-gas in the facility. The off-gas exhauster must be rated for continuous service and will be located in a totally enclosed very highly radioactive environment, where normal access is not possible. The location of the exhauster precludes maintenance access and as such, a very high degree of reliability is required. The supplier shall provide a complete off-gas exhauster(horizontal with split-casing) unit including base plate, motor, wiring, and conduits for installation at the plant. The exhauster assembly shall be furnished to conform to the dimensions and configuration per a purchase specification and is to be directly interchangeable with the existing exhauster assemblies and mounting frame. The exhauster housing and components shall be fabricated from stainless steel, type and grade suitable for the service and conditions specified above. All materials shall be furnished with Certified Material Test Reports (CMTR's) or Certificate of Conformance, as applicable. All materials shall be identified and certified by ASTM designation. The off-gas exhauster shall be rated at a normal flow rate of 500SCFM @ 14.7 psia and 68 F (Min 200SCFM @-60" WC and Max. 500SCFM @-90" WC). The suction and discharge of the exhauster will be 8 inches. The electric motor shall be 460VAC, 1200 rpm, 3 phase, 60 HZ, TEFC, Counter Clockwise rotation, totally enclosed chemical type motor. The supplier shall furnish a self-contained highly reliable lubrication system for the bearings. The system shall be mounted in the vicinity of the blower or blower skid and be suitable for the environmental conditions as described above. All lubrication piping/tubing shall have welded connections/fittings to the maximum extent. The anti-friction bearings shall be rated with a minimum life of 80,000 hours with continuous operation. The shaft/bearing seals shall be designed to prevent leakage into/out of the exhauster and prevent the bearings from coming in contact with the radioactive gas. The manufacture of the off-gas exhauster must be done under strict quality control, which will be reviewed by WSRC. The off-gas exhauster must successfully pass a pressure test (hydrostatic tested without mechanical internals), NDE and shop performance test (vibration test, etc.) before shipment. The casing hydrostatic test pressure shall be a minimum of 1 1/2 times the casing design pressure. A Firm-Fixed-Price Subcontract is contemplated. The Expressions of Interest must be received by WSRC on or before March 6, 2000. Reference tentative Solicitation Number 6A6545-LG on the envelope. An information copy of the expression of interest may also be sent by facsimile to Westinghouse Savannah River Company, Attention: Annette P. Midcalf, at (803) 952-6297. This is a request for expressions of interest only; it is not a request for a formal proposal. Posted 02/03/00 (W-SN421416). (0034)
